Help with my classic 84' 633CSi

[E30 F34R]

I have a 1984 633CSi owned by a Doctor, only 100,000 miles. German aftermarket rims. The only problem is it runs for 5 seconds, I have bought a brand new ECU and relays, fuel pump and sending unit. I wish I can figure it out. if you know any sort of problem for this model send me some info. It is also not getting any spark, that is why I got the ECU

Try the other area for vintage bmws for some info. This area is just about all e63 6ers.

how is it running for 5 seconds if it has no spark?

It is a relay I think, I had the SAME problem with my E30 a year after I got it. But the ones I got off a salvaged E24 might not have been good. It was doing everything the same as my E30. Then as soon as I changed it the problem was over. I think I will have to find a running E24 to get some good relays.
